I've been running a Terminator EFI on my LS engine, but I'm switching over to MPFI using the Weiand LS1 intake. I picked up the new in-tank pump setup, which is internally regulated at 58 psi. With the MPFI using 43 psi, is it just a matter of changing the pressure settings in the HP ECU to 58 psi, and let the ECU handle everything or ?
